Title: Multi-jack
Inventor: ROWE RICHARD E
IPC: A63F3/00
Filed: 2001-01-19
Abstract: A physical card game or electronically simulated card game is provided in which each of one or more players received cards which define two or more card hands, with at least one card in common. In one embodiment, the initial cards are arranged in a rectangular array with rows, columns and/or diagonals of the array defining the hands. Each hand can be played and/or evaluated using certain aspects of blackjack, poker or other traditional card game play or evaluation. At least some prizes or top winning outcomes for a round of play must include winning outcomes from at least two, and preferably from all, of the hands played by a given player. The relatively low odds of achieving highest-winning combinations on all hands makes it feasible to provide the game with relatively large prizes associated with such low-probability outcomes. In one embodiment, certain subcombinations of a player's cards, such as all initially-dealt cards, are evaluated for instant win combinations. In one embodiment, one or more additional cards may be dealt for use in defining some or all of said instant win combinations.

Title: Efficient internet service cost recovery system and method
Inventor: MCCOY JAMES
IPC: G06Q20/22
Filed: 2001-02-19
Abstract: The invention provides a distributed architecture where each portion of published content may be divided into numerous (i.e., hundreds or thousands) of small fragments, and scattered amongst the peer systems in the network. Retrieval of data may be accomplished by downloading the contents in parallel, locating a replica of an original fragment if a particular beer system serving the original fragment becomes overloaded or disconnected from the network. This architecture allows the invention to take advantage of the asymmetric nature of most user connections to the Internet by utilizing a collection of small agent applications (agents) running in parallel to deliver content rapidly across the network. The distributed load balancing system used by the invention functions as an agoric resource allocation system, with agents trading favors with a bartering network. By using pricing to signal resource contention, the agents can optimize the system according to local needs and obtain the most efficient usage from available network resources. The invention also keeps track of which users provide resources, content and indexing services within the network through an internal micropayment system which denominates internal tokens (credits) in the same resources needed to provide the services (i.e., disk space, bandwidth and CPU cycles). The distributed data service built on top of this micropayment system provides a reliable and scaleable method for peer-to-peer content distribution. In addition, by distributing accounting using a micropayment system denominated in payment-in-kind (i.e., barter), the system is less expensive to operate and easier to bootstrap than conventional systems. By using the resources themselves as the backing for the payment system instead of having a real currency serve as a proxy for these resources within the accounting system, the disadvantages plaguing conventional systems can be positively addressed.

IPC: E21B21/10
Filed: 2001-08-13
Abstract: An underground drilling method and apparatus generates intense pressure pulses at a location at the surface. The pressure pulses propagate down through a drill string to a drill bit. The pulses may be generated by creating water hammer in flowing drilling mud. Intensity of the acoustic pulses is increased in the bit nozzles. Vigorous pulsing of the fluid exiting the bit nozzles results in better cleaning of the hole bottom and faster drilling. The pulses may be used to drive the operation of various down hole tools . One type of tool has multiple pistons arranged in series. High pressure pulses move the pistons to generate strong mechanical vibration in the drill string. Vibration of the drill string may also reduce the friction between the drill string and the hole, resulting in lower torque requirements.
